Is it from Stephen King's Novel?

Two points before I've even read it:

1. It's spelled 'disease'. I for one would not read a script where the writer couldn't even be bothered to spell-check his logline.

2. The credited author should really be 'Richard Bachman'. Although King credited his own name to the TV movie of DESPERATION, a Bachman book. But he wrote the screenplay so I'm sure it was his decision.
